Question

I need to deploy basically the same stack to the US and EU two different AWS regions The correct way to do this is to have a multiple stack config files like `Pulumi us Production` and `Pulumi eu Production` right The other way is to do it in code but I don t think that fits nicely with the existing configuration model

You could encapsulate your entire stack into a `ComponentResource` and then instead declare 1 of those for each region at the top of your stack This would allow you to have a single `Production` stack Or just do separate stack configs

Hell you could encapsulate you entire stack into a `ComponentResource` as I mentioned and then you could have your config contain a list of regions to deploy into Then your `Stack` code could loop on those and declare an instance of your `ComponentResource` for each of them That way your `Staging` stack which might only need 1 region could just be a config change

I m thinking separate stack configs is the way to go

This is a tricky question because it s highly dependent on an environment and your requirements for the agility of your resources If your solution is using just 2 regions and will do for a long time Then Stack per region is good You can also make use of namespaces in config and have 1 stack for both regions like Joshua suggested `Pulumi production yaml` ``` us region config key value eu region config key value``` then in code ```us config = pulumi Config us region eu config = pulumi Config eu region ```

Yea I personally wouldn t want multiple stacks per region I m just imagining stacks going out of sync because now you need to deploy multiple times per environment per release
